Name: ACI: SPH3U Dynamics 45. Two sleds are tied together and are pulled across an icy surface with force of 121 N [S] pulling sled A. The mass of sled A is 23.5 kg and the mass of sled B is 38.5 kg. The coefficient of kinetic friction for each sled is 0.180. Calculate the acceleration of the sleds and the tension force acting on the connecting rope.

A 2.0 kg mass, placed on a smooth, level table, is attached by a light string passing over a frictionless pulley to a 5.0 kg mass hanging freely over the edge of the table. Calculate the tension in the string. Diagram FBDs B: Other Newton #2 x-dir'n B: x-dir'n A: y-dir'n B: y-dir'n A: Solve Page 27 of 29Name: ACI: SPH3U Dynamics 42. A student pulls a 60.0 kg toboggan with a force of 240.0 N along the horizontal. If this toboggan is connected with a horizontal rope to a second toboggan which weighs 40.0 kg and friction can be ignored. Find the acceleration of the toboggans and the tension in the rope between them.
